FREDRIOI( H. C. MEY, OF BUFFALO, NEW YORK.

CONVEYER.

SPECIFICATION forming part of Letters Patent N o. 408,733, dated August 13, 1889.

To all 1071/0711, it wwf/y concern:

Be it known that I, FREDRICK H. O. MEY, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Conveyers, of which the following is a specification.

This invention relates to that class of con`- veyers which are employed more especially for transferring coal from the coal yard or dock to cars or vessels, and which consist of an endless belt which is provided with an inclined portion, whereby the coal is elevated to the head of an inclined chute or deliveryconveyer, which conducts the material into the hold of the vessel or into the cars.

The object of my invention is to construct the conveyer in such a manner that its inclined or elevated portion can be shifted or adjusted to accommodate the location of the delivery-chute and the vessel, as circumstances may require. Y

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims. l

In the accompanying drawings, Acon sisting of two sheet-s, Figure l is a longitudinal section of my improved conveyer. Fig. 2 is a sectional top plan view thereof. Fig. 3 is a transverse section of the conveyer, taken through the tightener mechanism, on an enlarged scale. Fig. 4 is a fragmentary sectional elevation of the lowervportion ofthe carriage upon which the ti ghtener mechanism is mounted.

Like letters of reference refer to like parts in the several figures.

A represents the longitudinal base-rails of the conveyer.

B represents the endless conveyer,wl1ich is composed of transverse slats b, secured with their ends to endless chains b', and provided with overlapping side pieces h2, whereby the coal is prevented from falling over the sides of the conveyer.

O O represent the main sprocket-Wheels, around which the conveyer-chains -h run, and which are journaled at the upper ends of standards O2 C3, arranged at opposite ends of the base-.rails A. The intermediate upper portions ol the conveyer areA supportedv by sprocket-wheels d, which are mounted in Appiiciiion nega september s, 188s. seria No. 284,460. ci@ model.)

standards D D, secured tothe base-rails A,and the intermediate lower portions of the oonveyer are supported upon sprocket-wheels d.

E represents an elevated'tightener-frame, in which are mounted a series of sprocketwheels c e e2, around which the upper portion of the conveyer runs. This tightenerframe is rectangular in form, and consists of side pieces ff and round connecting-rodsf2 f3f4, secured with their ends to the side pieces f f and upon which the sprocketwheels e c e2 turn.

G represents a carriage or movable support, upon whichV the tightener-frame E is mounted, and whereby the same is shifted toward one or the other end of the conveyer. .The tightener-frame isjournaled in the carriage G by means of trunnions g g, formed on the side pieces of the tightener-frame and arranged in bearings g', formed in upward eX- tensions or standards G of the carriage. The tightener-fraine E is journaled in the carriage at or nea-r its center, and the sprocket- Wheels e e2 are arranged on opposite sides of the pivots of the frame, while the wheels e are arranged between said wheels. The carriage G is supported upon grooved rollers 7L, journaled in the lower end of the carriageframe and ruiming upon longitudinal tracks c', secured to the upper side of the base-rails A.

j j represent detent pawls pivoted to the lower end of the tightener-frame E and engaging with the curved ratchet-bars J, secured to the inner sides of the standards G of the carriage. These pawls hold the tighten'er-frame in position after the same has been swung on its pivots to tighten the conveyer.

G2 represents a hand-wheel secured to one of the trunnions g of the tightener-frame E, and whereby the latter is turned.

The endless conveyer runs from the sprocket-wheels O upwardly around the upper sprocket-wheels e, to form the elevatingincline K, thence around the inner sides of' the wheels e e2, and thence around the main sprocket-wheels C and back to the wheels O. The inclined chute,which is arranged underneath the overhanging upper portion ofthe incline K, and which delivers the coal tothe vessel or car, is shown by dotted lines in Fig.

ICO

1 at L. Upon releasing the pawlsj, the tightener-frame can be swung into the proper position to loosen the eonveyer, and the carriage with the tightener-frame can be moved back and forth between the main sprocket-wheels C C', to change the position of the incline K to suit the location of the coal or the vessel 01 ear. lVhen the carriage hasbeen properly placed, the conveyer is tightened by swinging the tightener-frame in the proper direction to move the upper sprocket-wheels e away from the stationary sprocket-wheels C and the lower sprocket-wheels e2 away from the stationary sprocket-wheels C', as represented in Fig. 1. ln this manner two bights or bends are formed in the upper portion of the conveyer, which are drawn in opposite directions by the upper and lower sprockctfwheels e e2 in tightening the conveyer.

The inclined portion K of the eonveyer is supported by sprocket-wheels m, which are mounted in brackets M, secured to the carriage G. The coal is dumped or shoveled upon the horizontal front portion of the conveyer at the foot of the incline K, carried upward by the latter and discharged upon the head of the inclined chute L, which latter conveys it into the vessel or ear. Instead of the inclined chute, a supplementary conveyer may be employed for eonveyin g theeoal from the head ot the incline K to the vessel or ear.

It is obvious that the eonveyer may be used for conveying grain and other material r S well as coal.

I claim as my inventionl. The combination, with the endless conveyer adapted to run around guide or sprocket wheels mounted in stationary supports, of a carriage, an elevated ti ghtener-frame pivoted at or near its center to said carriage, and

guide or sprocket wheels journaled at opposite ends of said tightener-frame, around which the upper portion of the endless conveyer runs, substantially as set forth.

2. The combination, with the endless oonveyer adapted to run around guide or sprocket wheels mounted in stationary supports, of a carriage G, a swinging tightener-frame E, mounted on said carriage, and guide or sproeket wheels e e e9', arranged in said tight-enerframe, substantially as set forth.

3. The combination, with the endless conveyer adapted to run around guide or sprocket wheels mounted in stationary supports, of a carriage, an elevated tightener-frame pivoted at or near its center to said carriage, guide or sprocket wheels journaled at opposite ends of said tightener-trame, around which the upper portion of the endless eonveyer runs, and means whereby said tightener-frame is held in position after being adjusted, substantially as set forth. Y

4. The combination, with the endless conveyer adapted to run around guide or sprocket wheels mounted in stationary supports, of a carriage, an elevated tighte n er-f rame pivoted at or near its center to said carriage, guide or sprocket wheels journaled at opposite ends of said tightener-'frame, around which the upper portion of the endless conveyor runs, and a pawl and ratchet, whereby said tightenerframe is held in position after being adj usted, substantially as set forth.

Witness my hand this 16th day of August, 1888.
